Abstract

A fluid removal system includes an operative sub-system, such as an ultraviolet (UV) light sanitizing system, that is configured to operate according to an operative cycle, such as a sanitizing cycle, and is configured to output an activation signal during the operative cycle. An actuator is operatively coupled to the operative sub-system and moveably connected to a fluid removal conduit. The fluid removal conduit is closed when the actuator is in a closed position, and opened when the actuator is in an open position. The actuator moves into the open position in response to the operative sub-system outputting the activation signal. Fluid, such as ozone, within a confined space is drawn into the fluid removal conduit when the actuator is in the open position and exhausted through an exhaust port.

First claim

What is claimed is:

1. A fluid removal system configured to remove at least one fluid from a confined space, the fluid removal system comprising:
at least one operative sub-system including an ultraviolet (UV) light sanitizing system that is configured to operate according to at least one operative cycle including a sanitizing cycle, wherein the at least one operative sub-system is configured to output at least one activation signal during the at least one operative cycle;
an actuator operatively coupled to the at least one operative sub-system and moveably connected to a fluid removal conduit, wherein the fluid removal conduit is closed when the actuator is in a closed position, and opened when the actuator is in an open position, wherein the actuator moves into the open position in response to the at least one operative sub-system outputting the at least one activation signal, and wherein the at least one fluid within the confined space is drawn into the fluid removal conduit and exhausted through an exhaust port when the actuator is in the open position.

2. The fluid removal system of claim 1 , further comprising a vacuum generator coupled to the fluid removal conduit, wherein the vacuum generator generates a vacuum that draws the at least one fluid within the confined space into the fluid removal conduit when the actuator is in the open position.

3. The fluid removal system of claim 1 , wherein the actuator comprises a flush valve of a toilet.

4. The fluid removal system of claim 3 , wherein the toilet is configured to be engaged by an individual to activate a wet flush in which a rinse valve and the flush valve are opened, and wherein only the flush valve is opened to provide a dry flush when the activation signal is output by the at least one operative sub-system.

5. The fluid removal system of claim 1 , wherein the actuator comprises one or both of a solenoid or a motor coupled to one or both of a plunger and drain plug of a sink.

6. The fluid removal system of claim 1 , wherein the at least one fluid comprises ozone within the confined space, and wherein the UV light sanitizing system includes:
a UV light control unit that is configured to output the at least one activation signal; and
a UV light assembly operatively coupled to the UV light control unit, wherein the UV light control unit controls the UV light assembly during the sanitizing cycle based on the at least one activation signal, and wherein the UV light assembly emits UV light to sanitize at least a portion of the confined space during the sanitizing cycle.

7. The fluid removal system of claim 6 , further comprising an engagement member that is configured to be manually engaged by an individual, and wherein the at least one fluid further comprises malodorous air within the confined space.

8. The fluid removal system of claim 1 , wherein the at least one operative cycle further comprises a turbulence detection period, wherein the at least one fluid further comprises water within the confined space, and wherein the at least one operative sub-system further comprises a computer onboard an aircraft.

9. A fluid removal method that removes at least one fluid from a confined space, the fluid removal method comprising:
operating at least one operative sub-system including an ultraviolet (UV) light sanitizing system according to at least one operative cycle including a sanitizing cycle;
outputting at least one activation signal from the at least one operative sub-system during the at least one operative cycle to an actuator that is operatively coupled to the at least one operative sub-system and moveably connected to a fluid removal conduit, wherein the fluid removal conduit is closed when the actuator is in a closed position, and opened when the actuator is in an open position;
moving the actuator into the open position in response to the outputting; and
drawing at least one fluid within the confined space into the fluid removal conduit when the actuator is in the open position.

10. The fluid removal method of claim 9 , further comprising generating a vacuum with a vacuum generator that is coupled to the fluid removal conduit, wherein the generating the vacuum draws the at least one fluid within the confined space into the fluid removal conduit when the actuator is in the open position.

11. The fluid removal method of claim 9 , wherein the actuator comprises a flush valve of a toilet.

12. The fluid removal method of claim 11 , wherein the toilet is engageable by an individual to activate a wet flush in which a rinse valve and the flush valve are opened, and wherein only the flush valve is opened to provide a dry flush during the outputting.

13. The fluid removal method of claim 9 , wherein the actuator comprises one or both of a solenoid or a motor coupled to one or both of a plunger and drain plug of a sink.

14. The fluid removal method of claim 9 , wherein the at least one fluid comprises ozone within the confined space, and wherein the UV light sanitizing system includes:
a UV light control unit that is configured to output the at least one activation signal; and
a UV light assembly operatively coupled to the UV light control unit, wherein the UV light control unit controls the UV light assembly during the sanitizing cycle based on the at least one activation signal, and wherein the UV light assembly emits UV light to sanitize at least a portion of the confined space during the sanitizing cycle.

15. The fluid removal method of claim 14 , further comprising manually engaging an engagement member to cause the moving, and wherein the at least one fluid further comprises malodorous air within the confined space.

16. The fluid removal method of claim 9 , wherein the at least one operative cycle further comprises a turbulence detection period, wherein the at least one fluid further comprises water within the confined space, and wherein the at least one operative sub-system further comprises a computer onboard an aircraft.

17. A vehicle comprising:
an internal cabin;
a lavatory within the internal cabin, wherein the lavatory comprises a toilet and a sink, wherein the toilet is configured to be engaged by an individual to activate a wet flush in which a rinse valve and a flush valve are opened;
at least one fluid removal conduit coupled to one or both of the toilet and the sink;
a vacuum generator coupled to the at least one fluid removal conduit, wherein the vacuum generator is configured to generate a vacuum within the at least one fluid removal conduit;
an ultraviolet (UV) light assembly within the lavatory, wherein the UV light assembly is configured to emit UV light into or onto one or both of the toilet or the sink during a sanitizing cycle;
a UV light control unit coupled to the UV light assembly, wherein the UV light control unit outputs an activation signal that activates and controls the UV light assembly during the sanitizing cycle;
at least one actuator operatively coupled to the UV light control unit and moveably connected to the at least one fluid removal conduit, wherein the at least one fluid removal conduit is closed when the at least one actuator is in a closed position, and opened when the at least one actuator is in an open position, wherein the at least one actuator moves into the open position in response to the UV light control unit outputting the activation signal, wherein fluid within the lavatory is drawn into the at least one fluid removal conduit when the at least one actuator is in the open position, and wherein the vacuum generator draws the fluid within the lavatory into the at least
